To all whom it may oonoern:

Be it known that I, ALFRED BREDENBERG, a citizen of the United States, and a resident of Champlain, Clinton county, New. York, have invented certain new and useful Improvements in Bookbinding-Machines, of which the following is a specification.

The present invention relates to book binding machines and more particularly to those machines in which groups of leaves or signatures which are to constitute the books are presented consecutively to instrumentalities designed to operate thereupon for performing one or more of the different steps in the binding and covering of pamphlets, magazines or other books.

The invention has for an object to provide improved mechanism for the purpose of performing certain of the operations involved in the course of binding and covering; and more particularly to provide an eflicient and reliable mechanism for applying a strip of crash or other fibrous material to the adhesive covered backs of books, pamphlets and the like.

Other objects will appear hereinafter in the following description or will be obvious therefrom.

The invention consists in the novel parts, improvements, mechanisms, combinations and arrangements herein shown and described and set forth in the claims.

The accompanying drawings referred to herein-and forming a part of this specification, illustrate one embodiment of the improvements, the same serving in connection with the description to explain the principles.

In the drawings, Figure l is a front view of a book binding machine, or a sufficient portion thereof to illustrate the principles of the present invention, certain mechanisms being omitted to which the present improvements are not specifically directed, but which can be supplied by reference to prior application Serial No. 292,407, filed on or about Dec. 19, 1905. Fig. 2' is a right end elevation of the parts seen in Fig. 1. Fig. 3 is a similar view-of certain parts of the strip handling mechanism detached from the other parts shown in Fig. 2 and indicated in a different position or stage of operation. Fig. 4 is a left-hand elevation of a detail of the construction shown in Fig. 1.-

Fig. 5is a rear elevation of the strip feeding rollers. Fig. 6 is a front elevation of the strip cutting devices. Fig. 7 is a. right-hand elevation illustrating the strip feeding devices on an enlarged scale. Fig. 8 is a plan view of a detail.

In the class of machines illustrated, there are a series of holders carrying books and connected to an endless device so that each holder travels from place to place in the machine bringing the book successively to the different mechanisms which are to operate on it. For example, the mechanisms may apply adhesive and then attach a narrow fibrous or textile strip to the moist adhesive and afterward apply a cover. The strip aids in more efliciently securing permanent connection between the dilferent leaves and p the cover.

In the present invention there is a strip applying mechanism in which the fibrous strip is adjusted to the book and then impelled reliably into position without mechanical pressure or contact between the applying mechanism and the adhesive covered part of the book. The strip might be constituted of cotton batting, crash, cloth or possibly paper. If this were mechanically pressed into place, adhesive would pass to the pressing part which would destroy its efficacy. 1

The desired objects are accomplished here in by the use in combination with the other parts of a pneumatic means for impelling the strip by air flow to move into position, thus obviating mechanical pressure; and with this pneumatic mechanism is combined means for feeding fibrous material and cutting off strips as required for successive books. Specifically, the strip holder hereof has hollow passages with openings adapted to be directed toward and in proximity to the adhesive covered portions of the book; and means for controlling the air flow, preferably so that the strip is first retained by suction until justified in proper position, the air flow being then reversed and compressed air issuing to forcibly drive the strip across the gap into place on the book.

The strip holder is preferred to be vibratable between a strip receiving position and a strip applying position adjacent to the tion will be more particularly set forth in the following description.

Referring now in detail to the particular embodiment of the invention illustrated in the drawings, some of the main portions of the machine, as to which per as no claim of novelty'is herein directed, will first be described and then the novel mechanism illustrating the present invention will be set forth.

In the first place the machine has a frame A carried on a base A. Certain specific frame parts that coiiperate with the strip handling mechanism will be hereinafter described in connection with the latter. In the upper part of the frame are upper guides B and lower 'des B shown in the form of channels wlth flanges turned toward each other adapted to receive between them traveling parts shown in the form of slides B, each of which slides, together with the book-holding-clamp to be described, may be considered as a carrier. As is usual there may be an extended series of such book carriers traveling one behind another around the guides or tracks B, B, and as before stated said ides may form a continuous or endless tree so that on completing the cycle each carrier stands at the position ready to commence a new cycle. One arrangement by which this last named result has been accomplished is to form the carrier track in two ong straight stretches, one on each side of the machine and the two stretches connected to each other at the ends by curved or irregular track portions; this arrangement being indicated in Fig. 2 of the drawings by the showing of tracks B, B, at the rear of the machine, within which is one of the book carriers comprising slides and clamps. With such extended length of travel of a book carrier each book may be sub ect to any desired number of operations by any desired number of mechanisms comprised in or mounted on the same machine, and the nature of the appropriate mechanisms to be so employed, has been'hereinabove indicated; only sufficient of the machine, however, being actually illustrated in the drawings hereof to enable a complete disclosure to be made of the improvements sought to be covered herein. On the outside of each of the slides is a suitble clamp comprising a front clam part 0 and a rear clamp part C, the re erence Z representing the book or more correctly speaking the group or collection of leaves or signatures which are to be constituted into a book, pamphlet or the like. The springs or other means for pressing toward each other the two clamp parts 0, C, are not shown as these will be well understood. The several carriers, of which five are indicated in Fig. 1, are not in the draw hereof connected to each other, and or the purposes of the present improvements they need not be connected, aseach carrier contaming book Z ma be moved onward by hand to the mechanism embodying the present improvements, the track or guides constitutm a means for or aid in positioning the boo It will, however, be understood that the carriers may be flexibly connected one to another in a train, so that a driving mechanism may be employed for simultaneously advancing all of the carriers, and so as to successively bring each of the books into operative position 1n each of the different mechanisms constituted in the machine.

The portions of the mechanism to which the present improvements more particularly.

relate will now be described, it being understood that, by means of an automatic adhesive applying mechanism or otherwise, a portion 0 each bookor leaf-group, namely the back edge portion, has been moistened with adhesive before the operation upon such book of the mechanism of the present invention.

A strip holder indicated generally by D is one of the elements of the illustrated embodiment of the invention, it com rising a to and fro moving member or rame D mounted for convenience to turn about a shaft or shafts D enabling it to oscillate to and fro. In operation the fibrous strip indicated at y is supported or held at the extreme upper portion of the strip holder D as seen in Fig. 2, and it is in the position shown in this figure that the mechanism is adapted to operate for applying the fibrous strip to the adhesive covered edge, that is the lowermost edge as shown, of the book Z.

Generally speaking the strip holder may be said to vibrate between the strip applying position shown in Fig. 2 and the stri re ceiving position, clearly indicated in Fig. 3; the material which is to form the strip being in the latter position both fed on to the strip holder and severed.

The strip holder and its operatlngmechanism and adjuncts including the air compression and suction control will first be described, and thereafter the strip cutting and feeding mechanism will be considered.

The strip holder D comprises in addition to its frame D a head d at the upper end. This is the important part and that upon which the strip is actually held or supported until its application to the book. The head at is movably connected to the frame D for purposes that will hereinafter appear, th s being accom lished through a pair of vertical guide rodb d passing through upper rod bearings d and also rod bearings (i con-' sisting of simple cylindrical holes in the frame D. The natural tendency of the head (1 is to move downward but it may be moved upward to difl'erent points by certain mechanism to be described. This mechanism includes a cam d mounted upon a longitudinal shaft X, which shaft may be considered the main driving part of the machine, it having cams and connections by which the several operations of the machine are performed automatically in improper order. Shaft X may be power driven by a pulley or any other convenient means. The cam 11 operates a train of mechanism or connections of which the last element engages a roller d secured or clamped by a device d upon the vertical rod d. Bearing against the roller d", see Fi s. 2 and 3, is a swinging member d mounted on a shaft ul having a fixed position in the machine, and the member d has an upper surface d upon which the roller (i may roll when the two are in operative contact. A link al is connected at its lower end to member at and at its upper end to one arm d of a bell crank lever mounted on a shaft cl having a fixed position in the machine, the other arm d of the bell crank lever being connected to an irregularly shaped rod d, whose conformation is unimportant except to enable it to clear the other machine parts when in operation. The other end of said rod is guided in its to and fro movements by an oscillating arm d pivoted to a shaft X having a fixed position in the machine; and the extreme end of the rod d is provided with a bearing surface such as the cam roller d adapted to bear directly on the cam d previously mentioned. The parts are kept in engagement by means of a spring which may for convenience be located at d. The cam 01 has four important surface portions, namely: d", the function of which is to present the strip holder head d to the strip-forming mechanism, as in Fig. 3; portion d", shown in operative position in Fig. 2, and serving to hold the head (1 in position for applying the strip y to the book Z; and d and d, which move the head d from one position to the other, and in doing so cause it to pass to a third and lower position and thus approach and recede from the plane in which the strip is formed in a direction transverse to that plane.

As shown, the mechanism for causing the to and fro movements of the strip holder consists of an adjustable arm D extending from a lug D formed on the strip holder frame tothe upper end of a lever D whose lower end is pivoted upon a shaft X having a fixed position in the machine. Adjustably connected to the arm D is a rod 1), its adjustment comprising a sliding block arrangement D with adjusting screws D for determining the position of the block and thereby regulating the effect that the rods movement will have upon the strip holder. The right-hand end of the rod D is provided with a roller D which bears against a cam D mounted on the same driving shaft X that carries the cam cl. To guide the end of the rod D which carries the roller D a swinging arm D is shown as connected at its upper end to the rod and at its lower end mounted upon the same shaft X upon which arm d is mounted. A spring D under tension extending from arm D to a lug D on the arm D, serves to pull arm D toward the right in Figs. 2 and 3, and thereby cause the roller D to constantly press .against the surface of its cam D Cam D has a portion D, which is inoperative p0 sition in Fig. 2 and serves to hold the rod D and the strip-holder D in the vertical position shown; and a portion I) which is seen in Fig. 3 to have permittedrod D and the strip holder D to move toward the right. In this Way the cam D effects the oscillating movement of the strip holder between strip applying position and strip receiving posltion, the latter being shown in Fig. 3.

In referring to the air controlling apparatus the invention in its broader aspects is not limited to air as other fluids may in whole or in part be available, and various means may be employed to render the same effective to produce the desired results. In the embodiment illustrated a control valve E is employed which has two or more positions, one position adapting it to connect the strip holder with a suitable compressed air supply, and another osition with a suitable exhausting means. he sources of compression and suction do not need to be shown in detail as they may be of any convenient type to produce air outflow and inflow. However, the pipe E may be considered as a source of exhaust and the pipe E as a source of compression, or a rotary blower could well be employed for both functions. Both of the pipes E, and E extend as shown to the valve E and there extends in turn from the valve a pipe E to which is coupled a flexible pipe or hose 0. the other end of hose 6 leading to the hollow interior of the strip holder head (i through a pipe e. The hollow head d shown in end view in Fig. 2 is seen in front view in Fig. 1, and in that figure is indicated in dotted lines the construction of the interior passages. Thus it shows a longitudinal passage 8 extending from end to end, its ends being plug ed, and showing a series of seven vertica passages e, each having a small nipple or nozzle at its upper terminus, the passage in which leads outward to the atmosphere. In this Way a series of openings which may be of any number and arrangement are provided in the otherwise fiat topmost surface of the head d, thus enabling either suction or compression to be applied to the fibrous strip supported on the head. It should be here mentioned that the purpose of the suction or inflow is to operate prior to the applicacation of the strip to the book for the purpose of securely holding the light material in its proper position on the stri holder and obviate its accidental disp acement. The purpose of the compression is that a forcible outflow of air (preferably in jets) may be caused to lift and bodily move the strip from its position upon the strip holder upward to its proper position upon the adhesive covered portion of the book, and to exert a sufficient pressure upon the strip to cause it to stick reliably to the adhesive and be thus united to the book so as to be carried thereby to the place where the cover is applied. Since no mechanical pressure is exerted upon the strip when in contact with the adhesive, littering and clogging up the parts of the strip handling mechanism with adhesive matter from the books is avoided. The presence of the fibrous strip not only more firmly binds together the back edges of the leaves, but also aids in uniting the group of leaves to the cover subsequently applied.

The valve E may be of any suitable construction, adapted to alternately connect the pipes E and E with the pipe E". As shown the valve has a stem 6 with an arm 6'' thereon, the arm having actuating means including a rod e extending as seen 1n Figs. 2 and 3 toward the right, its extremity having a roller e" contacting with a cam e mounted upon the same driving shaft X that carries the cams d and D The configuration of cam e is such as to cause the movements of the valve arm e' to operate the valve in harmony with the other parts of the mechanism. Cam surface e briefly opens compression pipe E while surface a holds the valve in position to open exhaust pipe E, and surface 6 holds the valve in position to open exhaust pipe E, and surface e holds the valve in position to close both pipes. A spring 6 may be so arranged as to pull downward upon the valve arm 6 for the purpose of keeping the parts under the influence of the cam e The cam revolves in the direction of the arrow. The compression surface a is seen to immediately follow the suction surface e so that the air flow is abruptly reversed. The valve momentarily passes through suction position when the roller 6 passes from surface 6" to surface 6 and remains closed until a is again replaced by suction surface 6 just prior to the dropping of head (Z and the swinging of the strip holder from right to left.

By way of introduction to a description of the strip cutting and feeding mechanisms, reference will first be made to so much thereof as is shown more or less diagrammatically in Fig. 3. The strip y is shown as not yet severed from the roll or supply Y, but as being cut or about to be out by a suitable cutting mechanism. As

shown, this mechanism comprises an upper u on a suitably mounted shaft f which is.

a so provided with a ear f of substantially the same size as t e knife. The gear meshes with a rack f so that as the knife f is moved alon the knife F as presently described, the ormer will be rotated, thus severing the strip 3 from the body Y of the fibrous material. The material Y coming from the spool passes in the direction of the arrow Fig. 3, and moves forward between the main feed roller G and a cooperating roller g, there being a supplemental small roller g for the purpose of giving the fibrous material greater extent of contact with the main feed roller G. And thereafter the material asses to the left between a pair of smal roller 51*, y located in close proximity to the knives F, f, said rollers g, 9* being driven throu h an intermediate gear g which in turn is riven by the rotation of the main feed roll G.

The feeding mechanism partly seen in Fig. 3 has its details shown in F igs. 4, 5 and y 7, Figs. 1 and 2 showing it as a part of the completely assembled machine. The main feed roller G is on a shaft 9 which has bearings in a fixed frame part g, there being a complementary frame art 9 at the opposite end of shaft 9. irectly beneath the feed roll G is feed roll g on shaft 9 journaled upon two vertically slidable members g extending through suitable holes in frame parts 9 and g and emerging therefrom to pass through coil springs 9 which are held under compression by washers or collars 9 located near the top of members 9 and confined in place by pins 9", this arrangement serving to yieldingly press roller g up against roller G. These rollers constitute the principal part of the feeding mechanism and the material receives its travel from them. Their illustrated construction is peculiar, and is superior for feeding such materials as have been referred to. Such construction is best seen in Fig. 5 in which roller G is seen to have a series of raised contact surfaces 9 in the nature of more or less broad flanges or circumferential ribs whose outer circumferences are roughened or milled to prevent slipping of the material, and between the surfaces 9 are substantial spaces; this construction being superior for feeding such materials as have been referred to. On roller 9 opposed to the raised contact surfaces 9 are a series of milled or roughened circumferential portions 9 between which are shown smooth se arating surfaces.

he rollers g, 9 previously referred to are seen in Fig. 7 where they are indicated as geared together by gears g, g and g", the last named being mounted on a shaft g" and geared to a gear 9 mounted on the same shaft 9' that carries the main roller G, so that all of these rollers are driven at the same surface speed.

There is a great advantage in having in addition to the large or main feed roll a pair of small positively driven feed rolls such as g, g for the reason that such small rolls may be brought into position closely adja cent to the cutting knives. The material is often extremely sleazy or flimsy and needs to be supported up to the point where it is actually delivered to the strip holder and severed. V

Adjusting means are shown for vertically adjusting the position of the rolls g 9 they and the gear g" being all mounted on vertically sliding members g which pass alongside the fixed frame parts 9 and g and at their upper ends are provided with screw adjustin devices 9 for the purposes referred to. nly one of the members 9" and. adjusting screws 9* is illustrated (in Fig. 7 but it will be understood that these parts will be duplicated at the opposite ends of the rollers. As shown, the screw 9 has two flanges 9 one below the other, and between said fianges project two lugs each forming a part of the member 9 When the handle 51" of the screw is turned the screw is driven down into the body of the frame part 9 and its flanges carry down the lugs 9! and with them the member 9 carrying the feed rolls g; g.

For driving the feed mechanism any convenient means maybe adopted, for example a pawl and-ratchet adapted to give a step by step motion. Thus in Fig. 5 a ratchet g is seen at the right end of shaft 9'. A pawl 9' engages ratchet 9, this pawl being seen in Figs. 2 and 4, in the latter of which figures it is seen to be pivoted at g to an arm 9 of a lever pivoted to a shaft X having a fixed position in the machine. The other arm 9 of the lever has pivoted to its extremity a rod g which extends d'ownwardly as shown in Figs. 1 and 2, and is conveniently connected to an oscillating arm secured on the same oscillating shaft i 2 that carries the arm I) hereinbefore referred to as constituting part of the strip-holder vibrating mechanism, so that the oscillation of the shaft will operate the pawl g and advance the ratchet wheel step by step. The degree of movement of the ratchet wheel may be varied so as to feed a strip proportional to the width of the books in any suitable way. As shown the rod 9 is connected to the arm 9 by a block {1 which is adjustable on the arm as by means of a screw 9- so that the extgnt of movement of the rod may be var1e Figs. 2 and 4 show a handle H whose purpose is to throw the pawl 9 out of operation when it is desired to stop the feed; this handle being pivoted at its lower end to a fixed frame part It and having pivoted at an intermediate point a rod h which extends therefrom to the pawl g. The handle is capable of being thrown forwardly or backwardly and when in the rearward position seen in Figs. 2 and 4 and also seen in Fig. 8, the pawl is operative. When the handle isreversed or thrown forwardly the pawl is lifted out of operative position. The handle is held in this position by a s ring h, Figs. 2 and 8, attached to a fixed rame part it, having a slot at Ii in which the handle moves. As shown, the handle also serves when moved forwardly to lock the shaft X against movement by the spring D and thus hold the strip holder in its forward position and render it inoperative.

The strip cutting mechanism is illustrated in detail in Figs. 1, 2, 3 and 6. The shaft f of lower rotary knife f has bearings upon a to and fro moving slide f, the said shaft f, it being remembered, having gear f at its far end automatically rotated by engagement with rack f as the knife f is moved along the knife F. The slide 1 may rest upon a fixed guide f and have a dove-tailed engagement therewith. Beneath and supporting guide i is a web 7" which connects the guide with a horizontal base portion f" which in turn is mounted on a pair of fixed frame parts f. The slide f is caused to travel to and fro by the following mechanism: A pitman f is pivoted at f to the slide f, the other end of the pitman as seen in Fig. 1 being connected to the upper end of an arm 7' which is secured to shaft X having a fixed position in the machine. The connection between the two may be such as to permit disconnection at will. by merely lifting the horn f forming an extension of pitman f, the latter being constructed with a slot which drops over the pin f in the yoke of the arm f for affording such detachable connection. A powerful spring f secured at one end to arm f and at its other end to a fixed part of the machine gives a tendency in the arm and connected parts to move toward the right. For opposing the spring, and imparting oscillating movements to the arm is emplgled a cam f mounted on the same shaft which carries the cam d D and e Cam f acts upon and is contacted by a roller f mounted upon an arm f secured to the same shaft X which carries arm f By this described arrangement the rotation of shaft X causes the to and fro movement of the cutter knife f, and its movemehts will be in harmony with the other parts of the mechanism by the proper positioning and contour of the cam f".

Fig. 1 shows the rotating cutter wheel at its left-hand position, and Fig. 6 at its righthand position. It has been'explained that the knife f is compelled to rotate as it travels, and that its relation with the stationary knife F is such as to sever a strip of the material Y. This cutting is done as the knife it moves leftward from Fig. 6 position, and t e shape of cam f" is such that the knife immediately returns to the right preparatory to a subsequent feeding and cutting operation. The cutting operation in the illustrated mechanism always occurs with the parts in the position seen in Fig. 3 where the extreme portion or strip of material is held between the strip holder and the knife F.

In operating the knives in the manner described the objection results that the unsevered part of the material is forced upwardly by knife f behind knife F where it is likely to remain. Obviously in order to properly feed for the next strip the material must stand sufiiciently below the knife F to certainly clear it during the feeding movements. To insure this an auxiliary device for forcing the material downward from the stationary knife is provided. As shown, this clearing device includes a movable member J seen in front view in Fig. 6 and in edge view in Fig. 2. The stationary knife F has two inclined cam grooves or slots at j, j, with which cam pins 7' engage, said cam pins being formed or secured on the member J which lies behind the knife F. The normal position of member J is sufficiently hi h that its lower edge will clear the rotary ife f in its to and fro movements as shown in Fig. 2. hen, however, the rotary knife after cutting a strip has passed back to the right as in Fig. 6, the slide 7 is caused to strike a projection j on a lever i thus deflecting said lever. The lever is pivoted at y" to a lug or standard 7" fixed to a convenient frame part, and the upper lever end is pivoted to a pitman which in turn is pivoted at j to a suitable portion such as the upper projection j of the member J ;'a spring j being employed tending to move the member J toward the right and restore the parts to normal position. This motion communicated b the lever 7' to the member J moving it to the left, causes the cam pins 7" to pass downwardly owing to the incline of slots 7' and thereby the member J is carried bodily downward to the position seen in Fig. 6. In this way the function is performed of restoring the supply of material to a sufficiently low position to be properly fed beneath knife F. When the knife f and slide f start toward the left for cutting, the lever j is at once released and the s rmg j effects the restoration of member to its normal position so that it will not interfere with the rotary knife.

The operation is as follows: Starting with the position of Fig. 2 the strip-holder D is in its upright position and the head a! is in its fully raised position. At this stage the cam-e operates to move the valve E so as to admit compressed air to the interior of the strip holder and thereby cause a forcible upward current which issues in jets at the top surface of the head :1 and drives the fibrous strip across the space between the head d and the book Z, and resses it into place simply by the force 0 the air current. The valve may then be closed so that there will be no air flow either way, and at the same time the head at will be lowered to its lowermost position which will bring it in contact with the upper bearin blocks d of the strip holder frame D. lifter or during the described downward movement of head (i the entire strip holder is moved or swung to the right by the cam D, carrying it from the position seen in Fig. 2 to that seen in Fig. 3. In the meantime fibrous material has been fed into position beneath the knife F. Then the cam d operates to elevate the head d of the strip holder preferably until it pinches or presses the fibrous material against the knife F. At this stage the cutting off of the strip is effected, during or after which the cam e actuates the valve E to connect the strip holder interior with the exhaust and cause the strip to adhere to the upper surface of the head cl. This action is continued through the following operations up to the time that the air is reversed for propelling the strip into contact with the book. The head d is then lowered by the cam 07 so as to separate it from the knife F, the strip y being carried with the head d, and thereupon the entire strip holder is by the cam D swung from the position of Fig. 3 to the left until it be comes substantially vertical, thus brin ing the head at immediately beneath the boo Z, it being understood that the book previously operated upon has been carried away and a new one, properly covered with adhesive at its lower edge, substituted. During or im mediately following this swinging movement the cam 0! again comes into operation to cause the elevation of the head at from its lowermost position to its highest position, namely that seen in Fig. 2, after which" the valve E is actuated to cut off the exhaust and admit a puff or flow of compressed air so as to propel the strip against the book, thus completing the cycle of operation. It should be stated ,that the blocks (1 carrying the rollers d, which coiiperate in the raising and lowering of the head d, are adskilled in the art.

It is to be understood that the invention in its broader aspects is not limited to the precise construction shown nor to any particular construction by which the invention has been or may be carried into effect, since many changes may be made in the details of the parts without departing from the main principles of the invention and without so crificin its chief advantages.
